BACKGROUND OF THE INVENTION
[0005] 1. Field of the Invention
[0006] The present invention relates generally to a power
generation device for exercise equipment, and more particularly to
an innovative device with a magnetic support component to cause
magnetic repellence between the swinging seat and the fixing seat
for a supporting effect in a stepper exercise machine.
[0007] 2. Description of Related Art Including Information
Disclosed Under 37 CFR 1.97 and 37 CFR 1.98
[0008] In prior art power generation devices for exercise
equipment, a driven wheel is configured to contact a flywheel,
which is driven by friction. However, in the prior art, after a
certain exposure to friction between the driven wheel and the
flywheel, the surface of the driven wheel will be inevitably worn
out, and the outer diameter will be reduced. Consequently, the
flywheel can no longer be driven by the driven wheel, and the power
generating function will disappear.
[0009] In consideration of the above problem, the industry has
developed an improvement that can maintain constant tight contact
between the driven wheel and the flywheel of the exercise equipment
through the pull or push of a spring component. However, in actual
usage of such prior art structures, it is still found that the
spring component, no matter its action is pull or push, will
quickly lose its elasticity due to tiredness after repeatedly
squeezing or traction, and consequently affecting the support
effect of the driven wheel. Hence, there is a problem of
insufficient durability and a short life span.
[0010] Thus, to overcome the aforementioned problems of the prior
art, it would be an advancement in the art to provide an improved
structure that can significantly improve efficacy.
[0011] Therefore, the inventor has provided the present invention
of practicability after deliberate design and evaluation based on
years of experience in the production, development and design of
related products.
BRIEF SUMMARY OF THE INVENTION
[0012] The power generation device for exercise equipment disclosed
in the present invention uses an innovative and unique magnetic
lifting component configured at corresponding positions on the
swinging end of the swinging seat and the fixing seat. Magnetic
force repels the swinging end of the swinging seat from the fixing
seat, and the swinging end of the swinging seat is elastically
lifted. As a result, the driven part of the power generating device
will constantly maintain tight contact with the flywheel of the
exercise equipment, such as a stepper machine. Based on the above,
the magnetic lifting component can exert a magnetic repelling
function without elastic fatigue and solid abrasion, and the
lifting mechanism of the power generation device of the exercise
equipment can have longer durability and much better quality, which
constitute a practical advancement.
[0013] Although the invention has been explained in relation to its
preferred embodiment, it is to be understood that many other
possible modifications and variations can be made without departing
from the spirit and scope of the invention as hereinafter
claimed.

DETAILED DESCRIPTION OF THE INVENTION
[0022] FIGS. 1 and 2 depict a preferred embodiment of the power
generation device for exercise equipment of the present invention.
The embodiment is for descriptive purposes only and shall not
restrict the range of patent application.
[0023] The power generation device A for exercise equipment
comprises a fixing seat 10. The fixing seat comprises a landing and
positioning part 11 and a component attachment surface 12. The
component attachment surface 12 has a hinge part 13.
[0024] The present invention includes a swinging seat 20,
comprising a joint and positioning end 21 and a swinging end 22.
The joint and positioning end 21 has a hinge connection part 23 to
be hinged with the hinge part 13 on the component attachment
surface 12 of the fixing seat 10, so that the swinging end 22 of
the swinging seat 20 can swing to various angles with the hinge
connection part 23 as a pivot.
[0025] The present invention also includes a power generating
component 30, attached to a preset position on the swinging seat
20. The power generating component 30 comprises a first and second
power generating unit 34, 35 and a driven part 32. The first and
second power generating unit 34, 35 both have an axis 33. The first
and second power generating unit 34, 35 are spaced with an
interval. The outside ends of the axis 33 of the first and second
generating unit 34, 35 are both configured with a rotating wheel
36. The driven part 32 is a ring-shaped component (can be a rubber
ring) winding on both the rotating wheels 36 configured on the axis
33 of the first and second power generating unit 34, 35, so that
the axis 33 of the first and second power generating unit 34, 35
can rotate simultaneously under the drive by the driven part
32.
[0026] There is also a magnetic lifting component 40, configured at
corresponding positions on the swinging end 22 of the swinging seat
20 and the component attachment surface 12 of the fixing seat 10.
The magnetic lifting component 40 shall be configured to cause
magnetic repelling between the swinging end 22 of the swinging seat
20 and the component attachment surface 12 of the fixing seat 10,
so that the swinging end 22 of the swinging seat 20 can be
elastically lifted. The detailed structural configurations of the
magnetic lifting component 40 is described as below in combination
with the attached drawings.
[0027] A magnetic lifting component 40 disclosed in FIG. 2,
comprises a first magnet 41 configured on the swinging end 22 of
the swinging seat 20 and a second magnet 42 configured on the
component attachment surface 12 of the fixing seat 10. The
corresponding sides of the first magnet 41 and the second magnet 42
are configured to have the same magnetic poles so as to cause
magnetic repulsion.
[0028] A magnetic lifting component 40 otherwise disclosed in FIG.
3, comprises a magnet 43 configured on the swinging end 22 of the
swinging seat 20, and an electromagnet 44 configured on the
component attachment surface 12 of the fixing seat 10. The magnetic
poles of the electromagnet 44 and the magnet 43 on their
corresponding sides are configured to be the same when there is
electric connection, so as to cause magnetic repulsion.
[0029] The above structures constitute the present invention. Below
is a description of the working conditions of a preferred
embodiment of the present invention.
[0030] Referring to FIG. 2, in actual application of the power
generation device for exercise equipment A, the driven part 32
winding between the rotating wheels 36 configured on the first
power generating unit 34 and second power generating unit 35
tightly contacts one side of the flywheel 50 of an existing
exercise apparatus. In this way, when the flywheel 50 rotates, it
will drive the driven part 32 to run, and further drive the
rotation of the first and second power generating unit 34, 35 to
produce electricity. The core of the present invention is the
magnetic lifting component 40 configured between the swinging end
22 of the swinging seat 20 and the component attachment surface 12
of the fixing seat 10 to cause a magnetic repulsing force, so as to
elastically lift the swinging end 22 of the swinging seat 20. As a
result, the driven part 32 will constantly maintain certain
tightness and exert its driving function.
[0031] It is to be supplemented that, apart from the configurations
of a first power generating unit 34 and second power generating
unit 35 as disclosed above, the detailed constitution of the power
generating component 30 can also be like the generating component
30 disclosed in FIG. 4, which comprises only one single power
generating unit 34, and in which the driven part 32B is a rotating
wheel configured on the axis 33 of the power generating unit.
[0032] Furthermore, the power generating component 30 shown in FIG.
5 also comprises a first power generating unit 34 and a second
power generating unit 35 which are spaced with an interval. The
first and second power generating unit 34, 35 comprise a rotating
enclosure 37 to rotate simultaneously with the axis 33. On the
periphery of the rotating enclosure 37, a ring groove 38 is
configured. The driven part 32C is an elastic ring (such as rubber
ring) winding on the ring groove 38 of the rotating enclosures 37
of the first and second power generating unit 34, 35. The driven
part 32C is driven by the flywheel of the exercise equipment
through frictional contact.
[0033] The power generating component 30 shown in FIGS. 6 and 7 is
a variation of the configuration disclosed in FIG. 1. Difference of
this embodiment is that the power generating component 30 only has
one power generating unit 34B. The driven part 32D is also in the
form of a ring component (can be a rubber ring) winding on the
periphery of the rotating wheel 36B configured on the end of the
axis 33 (disclosed in FIG. 7) of the power generating unit 34B.
Apart from that, in this embodiment, the shapes of various outside
parts of the fixing seat 10 and swinging seat 20 are also different
from the shapes of the embodiment disclosed in FIG. 1.about.5.
[0034] The power generating component 30 shown in FIG. 8 is one
single power generating unit and has a rotating enclosure 39. The
outside of the rotating enclosure 39 is wound by a driven part 32D
in the form of an elastic ring. This embodiment is characterized by
two frame boards 24 configured on the swinging seat 20 with an
interval. The rotating enclosure 39 is held between the two frame
boards 24, and the ends of the axis 33 are fitted in the axis holes
25 on the frame boards 24 so that the rotating enclosure 39 can
rotate. The driven part 32D has one side protruding out of one side
of the two frame boards 24.
